E.g. $ sudo vm start u18-unh-00 Starting u18-unh-00 * found guest in /vms/u18-unh-00 * booting... $ ps waux|grep bhyve root 3430 33.3 0.0 4247640 29376 0 SC 18:23 0:02.56 bhyve: u18-unh-00 (bhyve) ctuffli 3441 0.0 0.0 12904 2616 0 S+ 18:23 0:00.00 grep bhyve $ sudo lldb (lldb) attach -p 3430 Process 3430 stopped --=20 You are receiving this mail because: You are the assignee for the bug.=
